Abstract
An application server has a custodian application running thereon. The custodian application instantiates a cryptographic microservice. The custodian application transmits a first request message to a centralized KMS requesting a data encryption key. In response, the centralized KMS returns the data encryption key. The custodian application transmits a second request message to the cryptographic microservice application. The second request message includes a request for a wrapping certificate from the cryptographic microservice application. The custodian application receives the wrapping certificate. The custodian application transmits a third request message to the centralized KMS. The third request message includes the data encryption key encrypted via the master-level tenant key and the wrapping certificate. The custodian application also receives the data encryption key encrypted via the wrapping certificate and transmits it to the cryptographic microservice application. The cryptographic microservice application unwraps the wrapped key using the wrapping certificate.
